I've got several transmission fluid leaks on my '74 Plymouth Scamp, /6 auto - and after cleaning things up, it appears one of them is the extension housing snap ring cover gasket. I'm having a heck of a time trying to find a part number or even the correct name for it. Does anyone know if this gasket is available? A part number or source for it would be amazing. Or do I need to make my own gasket for this?
